writeBoolean

This method writes a Java boolean value to an output stream. If
value is true, a byte with the value of
1 will be written, otherwise a byte with the value of 0 will be
written.
The value written can be read using the readBoolean
method in DataInput.

writeByte

This method writes a Java byte value to an output stream. The
byte to be written will be in the lowest 8 bits of the
int value passed.
The value written can be read using the readByte or
readUnsignedByte methods in DataInput.

writeBytes

This method writes all the bytes in a String out to the
stream. One byte is written for each character in the
String.
The high eight bits of each character are discarded, thus this
method is inappropriate for completely representing Unicode characters.

writeChar

This method writes a Java char value to an output stream. The
char to be written will be in the lowest 16 bits of the int
value passed. These bytes will be written "big endian". That is,
with the high byte written first in the following manner:

writeDouble

This method writes a Java double value to the stream. This
value is written by first calling the method
Double.doubleToLongBits
to retrieve an long representing the floating point number,
then writing this long value to the stream exactly the same
as the writeLong() method does.
The value written can be read using the readDouble
method in DataInput.

writeFloat

This method writes a Java float value to the stream. This
value is written by first calling the method
Float.floatToIntBits
to retrieve an int representing the floating point number,
then writing this int value to the stream exactly the same
as the writeInt() method does.
The value written can be read using the readFloat
method in DataInput.

writeShort

This method writes a Java short value to an output stream. The
char to be written will be in the lowest 16 bits of the int
value passed. These bytes will be written "big endian". That is,
with the high byte written first in the following manner:

writeUTF

This method writes a Java String to the stream in a modified
UTF-8 format. First, two bytes are written to the stream indicating the
number of bytes to follow. This is written in the form of a Java
short value in the same manner used by the
writeShort method. Note that this is the number of
bytes in the
encoded String not the String length. Next
come the encoded characters. Each character in the String
is encoded as either one, two or three bytes. For characters in the
range of \u0001 to \u007F, one byte is used.
The character
value goes into bits 0-7 and bit eight is 0. For characters in the range
of \u0080 to \u007FF, two bytes are used. Bits
6-10 of the character value are encoded bits 0-4 of the first byte, with
the high bytes having a value of "110". Bits 0-5 of the character value
are stored in bits 0-5 of the second byte, with the high bits set to
"10". This type of encoding is also done for the null character
\u0000. This eliminates any C style NUL character values
in the output. All remaining characters are stored as three bytes.
Bits 12-15 of the character value are stored in bits 0-3 of the first
byte. The high bits of the first bytes are set to "1110". Bits 6-11
of the character value are stored in bits 0-5 of the second byte. The
high bits of the second byte are set to "10". And bits 0-5 of the
character value are stored in bits 0-5 of byte three, with the high bits
of that byte set to "10".
The value written can be read using the readUTF
method in DataInput.
